Part Number: AM2634
Other Parts Discussed in Thread: SYSCONFIG

Hi Champs,

Customer need to use EPWM24 as a synchronization source, why the option is only up to EPWM23? 

etpwm.h has the definition of EPWM24 synchronization source, but it cannot be configured in sysconfig.

Could you please help to check this? How could customer use EPWM24 as a synchronization source? Thanks!

Best Regards,

Julia

    Hi Julia

    In the TRM the PWM Sync In Sources are given as mentioned same to Syscfg:

    Please check in section --> 7.4.5.4.3.4 ePWM SYNC Selection

    Is it possible for the customer to use a different PWM?

    My suggestion is use the same configuration and duplicate it with Actions disabled on another PWM and it can be used a sync source?

    The definition might be present in the SDK might be source for future devices, I will check with SW team and confirm if this needs to be removed from the SDK or may be add a comment.

    Thanks & Regards
